also, they develop and add to the flavor of what you cook that nonstick pans never will. My inexpensive item though was a stupidly cheap chef's knife from Ikea. I needed one after moving into my first apartment and I was getting some furniture there (the futon wasn't bad either, for what it was,) and I still have the knife around even after upgrading to a wustoff.
it was like twenty bucks. and with care it still performs like a champ.

Carbon steel is equally wonderful, esp since you can get much thinner pans that heat up lickedy split. I'd recommend trying one!
